  • ½ cup (65g) all-purpose flour

  1. Preheat oven to 350°F (175°C). Line a 9x13 inch baking pan with parchment paper, leaving an overhang.
  2. Combine graham cracker crumbs, melted butter, and sugar in a medium bowl. Press firmly into the bottom of the prepared pan.
  3. Bake for 8 minutes to set the crust.
  4. In a large saucepan, melt butter over medium heat. Remove from heat and whisk in sugar, cocoa powder, salt, and vanilla.
  5. Whisk in eggs one at a time, then gently fold in the flour until just combined. Do not overmix.
  6. Pour the brownie batter over the pre-baked graham cracker crust. Spread evenly.
  7. Sprinkle mini marshmallows evenly over the brownie batter.
  8. Bake for 25-30 minutes, or until a toothpick inserted into the brownie portion comes out with moist crumbs. The marshmallows should be lightly golden brown.
  9. Let cool completely in the pan before lifting out using the parchment paper overhang. Cut into bars. Enjoy your smores brownie bars!
